I’ve been asked that dreaded question again:
Q: More Mega-pixels is better, right?
A: Sure, if you can afford an H4d-200MS or 645DF & IQ180 Medium Format…with a lens or two.
Q: What’s Medium Format?
A: * Sigh *

Nikon Canon Nikon Canon ...

Has aggressive marketing and consumerism made potential DSLR buyers really believe that N is better than C or C better than N thanks to the Mega-pixel count of the latest release? Are Mega-pixels the be all and end all buying factor of the perceived quality of a digital camera and thus the only basis for a purchasing decision? It’s as bad a question as the “What camera is better? Nikon or Canon?” Define “better”?

What about Sony, Sigma, Pentax, Kodak, Olympus, Fuji, Samsung, Panasonic, Leica, Hasselblad, Phase One, Mamiya, Zeiss etc. Are they no good? Never heard of them? Won’t consider them?

Sensor Sizes (Not to scale) Image courtesy Wikipedia. Click on the image to go their comprehensive sensor article.

What about the actual sensor dimensions used in various iterations of all these brands and cameras?
What about the TYPE of sensor, the design and the technology of the actual sensors that record the image? There are many different types of sensors each with their own unique design and improvements over the years. How does the manufacturers in-camera image processing software algorithms shape up? Do you need to shoot low light without flash? Are you only shooting in natural light. Wildlife, events, PJ? How about studio work?
Are lenses/glass quality also not part of this equation? Do you want one lens that goes from wide angle for landscapes to 600x zoom for spotting the tick on a Warthog’s butt at 200 meters? It’s ok, it’s got anti-shake! Will it still be as sharp on a P&S 600mm 12Mp with 1/1.8″ sensor (24.7mm²) as on a full frame 24Mp with 600mm f/4? with a 35mm (370 mm²) sensor? What about the signal-noise ratio? The larger sensor also has less clipping.

Based on ones need, I can make a purchasing suggestion wrt body, make, model, lens and sensor type/mega-pixel choice. It’s about the intended use, not only the Mp. Get a FF DSLR and the 4 or 5 lenses you will need to go from Ultra Wide Angle to Super Zoom at 800mm. Now try sneak it on as hand luggage on your way to the Serengeti.

There is not one definitive answer unless money is no object. Note that these two cameras are used in mostly studio and product photography and may not be ideal or practical for wildlife, astronomy, your next fishing trip (or event work?) due lens selection and body size, practicality and even weather resistance:

Who here has seen (drooled over) the Hasselblad H4D-200MS yet?

Hasselblad H4D-200MS - CCD based back.

Or the Phase One 645DF with IQ180 Digital Back?

Phase One 645DF - CCD based back.

In order to answer the More Mp is better question:

What is your intended use of the camera? (Holiday snaps to billboard advertisements of supercars/models).
What print size do you want? (Postcard or a wall mounted A1 Canvas?)
What is your budget!? (How deep are your pockets?)
Have you got old AF or MF lenses from the film days and what brand? (Saving money on glass allows you to spend more on new body technology)
How big are your hands and how strong is your back? (Good glass weighs a tonne)

You can see where I am going with this… (continue reading…)

Was commissioned by Simon Says Communications to shoot casual, candid and fun shots for Merck, who have sponsored this event for 19 years! Up at 3am to arrive at 4am. The first hour was dark, shooting in artificial light, no flash, so the f/4 and f/2.8′s are perfect for that at around ISO 400-1600. If you don’t have the budget for an f/2.8 zoom, a 50mm f/1.8 would be ideal for the type of close range work in poor light. The rest of the day I shot with my 12-24mm and the 70-200mm on two bodies. Man was it cold and wet and grey and overcast. The lens hoods were catching the moisture in the air and the droplets were starting to freeze. My gear held out despite the bighting cold and slight drizzle. Shot with Nikon bodies, SB-800 speeedlights, Tokina 12-24mm f/4 ATX Pro DX, Sigma 28-70mm f/2.8 AF-D, Sigma 70-200mm f/2.8 HSM. No VR and mostly hand held or on a Manfrotto 190XPROB tripod

Thank you to Kerry and her team for a fun shoot. Hope those runners didn’t cramp up too much thanks to Slow-Mag®!

Gear I use: Bodies: Nikon D-SLR’s / Lenses: Nikon, Sigma, Tokina, Vivitar /
Filters: Hoya UV & Polarizing / Flash: Nikon Speed-lights / Bag: Lowe Pro /
Tripods & Heads: Manfrotto / Grips and Batteries: Phottix
Editing Plug-in: Topaz Labs for Noise Reduction, HDR.

OK. So you have a yearning to try Macro work? Ladybugs, Mantids, Flowers or anything else that springs to mind. But that $1000.00 105mm f/2,8 VRII Macro Lens is just a little beyond the budget? You should have gotten an 18-55mm Kit lens with your DSLR or you have a nice 28-70mm f/2.8? Your not sure if spending so much money will be worth it? There are a number of solutions. You can buy an adaptor ring or reversal ring, which mounts into your DSLR body and the other end is threaded so that you can reverse your lens and screw it into the adaptor. This effectively turns your lens into a macro lens. Sure there will be no metering. Focus and exposure is manual and you will have to determine the correct exposure, by trial and error. Set mirror lock-up and use the best tripod you can afford. A small shutter release is also a definite must. All of which prevent camera shake and blur. So choose an object that is stationary, like a coin, or flower or rings. This reverse ring will cost you all of maybe $25-00. Don’t like it? Too much effort? Then macro is probably not for you. You see, even with a dedicated Macro lens you will eventually only manually focus. Focus and composition is so critical on macro’s that you can’t let the camera’s AF do it for you. Whilst the exposure is auto on such a lens, you might sill need to add flash or fill light to your subject. Trust me, its better to set that up manually too, you will want to control the light direction and intensity more often than not, meaning off camera flash. iTTL or eTTL is pretty pointless then, unless you insist on running it using an ext cable. There are many online macro tutorials, all I’d like to say here is go cheap first. Go manual. You have more control and if you find that going from stationary objects to moving beetles or bees becomes near impossible, yet you are still keen to try, then go for a few extension rings. You get manual and automatic version of this. If you can afford it, take the auto’s. It’s one less thing to worry about when you start chasing live subjects. Sure you can throw the bug into the deep freeze for 5 minutes and haul him out in a state of narcosis, but you don’t have a fridge in the veld 100 miles from home. So you need to practice before you hit the road.

This image was shot with a set of Phottix AF Macro Tubes coupled to a Sigma 28-70mm f/2.8 EX DG and a YongNuo YN-460 II Speedlight that was fired with a set of Phottix Tetra Triggers and an IR Remote Control. Outlay for flash, AF ext tubes, batteries, triggers and IR RC (excluding camera and lens) about $390-00 vs a dedicated 105mm f/2.8 VR macro lens of about $1000-00, no flash or batteries…

A word of caution, the smaller macro lenses around 40/50/60mm tend to minimum focus (1:1) TOO close to the subject. The front element is literally a few cm’s or even a few mm’s away from the subject, and if it’s a live subject, it’s scared off long before you can focus. This is true for extension tubes combined with normal short tele lenses. But at least you haven’t made a $700-00 to $1000-00 mistake.  This then is the attraction of the huge 180mm Macro’s. 40cm / 18″ closest focusing distance but thats one huge chunk of glass, and thus heavy to lug around. In everything there are compromise, especially photography.

If you are going to buy a real macro lens, also don’t bother with those 70-300mm “macro” lenses. You normally don’t get 1:1 lifesize ratios, they tend to be 1:2 or often 1:3. Maybe you have one of these lenses. Go right ahead, switch it to macro and try it. Not what you expected right? If macro is for you, get at least a 100mm (Canon) or 105mm (Nikon) mount from Canon, Nikon or Sigma. I use a 180mm f/3.5. It’s a chunk of glass weighing in at 2.1 lbs (965g) and no OS/IS/VR. (ETA: Sigma have released an OS f/2.8 version in Jan 2012.) Tripod only unless you have arms like Arnold…which I don’t! But it’s closest focus distance is 18″ from the subject. Get something in the 100-150mm range. Thank me later

Latest entry over at DailyAwards. Doubt it will do well but I like it and I like these cheeky blighters. Shot with a Sigma 75-300mm f/4.5-5.6 APO Macro for Nikon.

Vivitar VIV-500-6.3 500mm f/6.3 Mirror Lens

Note to readers: Please leave a comment! It would be nice to know where you are from and if the article helped you in any way!

Christmas 2009. A new Vivitar 500mm f/6.3 DX Series 1 Mirror Lens. I’ve always been fond of them.

A lightweight (1.4 lb – 651 g) manual focus, multi-coated, catadioptric (reflex), fixed aperture “Super” Telephoto which, despite the “DX” label, can be used on full and small frame DSLR sensors as well as on regular 35mm film SLR’s. On the D90, with it’s DX sensor and 1.5x crop factor, that’s an effective 750mm! Make sure you are a good 15+ meters from your subject unless you want to shoot that Lion’s eyeball. These mirror lenses can be attached to virtually any (D)SLR using common T-Adapters. My first set of images can be found at the end of this post. You deserve to see what some lens manufacturers may not want you to see and thus why reviewers (and others) often unfairly malign these marvellous mirrors…

Sigma 28-70mm F2.8 EX DG

Today I became the proud owner of a Sigma 28-70mm f/2.8 EX DG for Nikon AF-D.
Sigma MSRP $1100 US
Initial Street Price $499 US
Final Street Price $349 US (December 2009)
The full frame (Sigma’s DG Technology) lens that is effectively a 42-105mm f/2.8 on the D90′s DX sensor. Ideal for daily and portrait work. Sigma have for years made outstanding lenses. This one is no exception. This lens has sadly been discontinued and replaced by the slightly wider 24-70mm f/2.8 EX DG with MACRO. (MSRP $1400 US! Initial Street Price $569 US December 2009)
Here are it’s technical specs from Sigma’s own website recorded for posterity before they take it down: A review will be posted here in due course. (continue reading…)
